Image Crusher is Image Compression Software for the Opencart eCommerce Platform.
This module analyses the images on any Opencart powered site and optimises them where possible without degrading quality.
It Makes sites load faster and rank higher in Google to generate more sales.
– Upload a jpeg/png from your computer and see how much it is optimised.
– enter catalog/demo and click crush images and watch as the images are compressed.
It also compresses all of the jpegs & pngs that you upload through the image manager in the Opencart admin. You control the level of compression through the admin page.
This reduces file size on the front end and loads sites faster for your users.
The compression is handled by the native GD Graphics library
Once uploads are successful, Image Crusher will display a popup showing the percentage saving of the file size after optimisation.
You have the option to set the level of compression and also the ability to turn it off when it is not needed.
Q: Can Image Crusher compress images that are live on my site now? A: Yes, you enter a folder name and the Module will scan all the images in this directory and all subdirectories for images. It will then compress all of the jpegs & pngs it finds.
Q: Will this work for all image types? A: This version of Image Crusher is for JPEG’s and PNG’s only.
Q: What happens the original file? A: The original file stays on your computer, untouched.
Q: How does the Image Crusher know how to reduce the file size? A: The actual compression of the images is carried out by the GD Graphics library. This is part of php and the functions analyse the images and strip out things like comments and meta data. Therefore your image can be reduced in size without lowering quality.
Q: Can I set the compression level A: Yes, this can be set from 1-10 in the admin
Q: What compression level do you re-commend? A: Level 7 is a good choice for sharp images that are small in size.
Q: What if I upload another file type? A: If you upload any other image type it will simply be processed as normal and the Image Crusher will not touch it.
Q: What if the image quality is poor? A: If you select Level 10 compression your images will still be good as the module applies a threshold in the background to ensure the image quality does not come out too bad.
